Channel 4 has requirements to provide distinctive programming that reflects UK culture through shows like Gavin and Stacey, while staying within watershed hours and content restrictions. It is commercially funded through advertising compared to the BBC which is funded by the license fee. E4 targets 16-34 year olds with trendy programming like Pretty Awesome Thursdays featuring American sitcoms. In contrast, BBC3 provides innovative content for younger audiences focusing on new UK talent. Scheduling shows in prime time helps attract the target audience, but on demand services reduce the importance of prime time slots.
